Applied the series. Thanks!

Out of curiosity, what tests does gpmi-nand.c now pass/fail?

Also, is it time to yank / fixup some of these comments from
gpmi-nand.c?

 ...
 * FIXME: The following paragraph is incorrect, now that there exist
 * ecc.read_oob_raw and ecc.write_oob_raw functions.
 *
 * Since MTD assumes the OOB is not covered by ECC, there is no pair of
 * ECC-based/raw functions for reading or or writing the OOB. The fact that the
 * caller wants an ECC-based or raw view of the page is not propagated down to
 * this driver.
